Is necessary having a static ip for my mail server ?

Well, technically, not necessary. You can send/receive emails with a dynamic IP address. But the problem is, most spammers use dynamic IP address to send spams too, so many ISPs block dynamic IP addresses directly to stop spam. That's why a static IP address becomes "necessary".

Since i could send a message from thundrebird to my mail server via internet but i could't to another domain (like gmail) that means my problem with static ip

But this message what does it mean ?[xx.xx.xx.xx] The IP you're using to send mail is not authorized to 550-5.7.1 send email directly to our servers. Please use the SMTP relay at your 550-5.7.1 service provider instead.

You should read URL in above message to understand why email was rejected.
